a. Anna: That's right. It's so shocking that people would do that for farming.

b. Huong: Yes, it's terrible. I heard they are often started on purpose to clear land.

c. Anna: Have you seen the news about the fires in the rainforest?

a. Aisha: I don't know, but if we keep cutting them down so fast, maybe.

b. Maria: Do you think we'll ever run out of trees?

c. Maria: I hope not. The planet needs them to produce oxygen.

a. Sofia: My dad was talking about a new road being built near our town.

b. Sofia: Yeah, they have to cut down a lot of trees for it. I feel bad for the animals that live there.

c. Linh: Oh? Is it going through a wooded area?

a. Clara: It's crazy to think that something like rain can be so damaging.

b. Yumi: I know. It's a bit scary. I wish everyone would care more about the environment.

c. Clara: Me too. We all need to do our part to protect the world we live in.

a. Fatima: I'm trying to use less plastic now. It feels like a small thing, but it helps.

b. Fatima: It's crazy how much plastic we use every day.

c. Elena: I know. And most of it ends up in the ocean, hurting the fish and other sea animals.

a. Isabel: Yes, in many parts of the world, people don't have enough clean water.

b. Trang: We should be careful not to waste water when we brush our teeth or take a shower.

c. Trang: I learned that using too much water is a problem. It's called water scarcity.

a. Naomi: I saw a program about coral bleaching. It looks so sad.

b. Naomi: That's terrible for all the fish and other animals that live there.

c. Leila: It happens when the water gets too warm. The coral loses its colour and can die.

a. Hannah: We should only buy what we need so that less food goes in the trash.

b. David: Yeah, we throw away a lot of food that we could eat.

c. Hannah: My dad told me that we have a problem with food waste.

a. Omar: That's called the urban heat island effect. Cities with lots of buildings and cars get very hot.

b. Tuan: It's so hot today, but not because of the sun. It's because of the buildings.

c. Tuan: I guess having more parks and trees in cities would help.

a. Arjun: I think they're things farmers use to kill bugs on their plants.

b. Arjun: And they can get into the water and make it dirty for us to drink.

c. Luca: So they're not good for the environment or for people.

d. Luca: Do you know what pesticides are?

e. Luca: That's right. My mum said they can also hurt the soil.

a. Daniel: Exactly. If we keep taking too many, there won't be any fish left.

b. Minh: My dad told me that some kinds of fish are disappearing.

c. Minh: So the fish don't have time to have babies and grow.

d. Minh: We need to be more careful about how many we catch.

e. Daniel: Oh, that's because of overfishing. We catch too many.

a. Ahmed: That's because the ice in the Arctic is melting.

b. Kenji: That's terrible for the polar bears and other animals that live there.

c. Kenji: Why is the ice melting?

d. Ahmed: Because of global warming. The Earth is getting warmer, so the ice is turning to water.

e. Kenji: I saw a picture of a polar bear on a small piece of ice.

a. Miguel: I saw a TV show about all the rubbish in the ocean. It was so sad.

b. Nam: Yes, they can eat the plastic and get sick.

c. Nam: I know. The plastic we throw away ends up in the sea.

d. Miguel: It makes me want to use less plastic from now on.

e. Miguel: It's bad for the fish, isn't it?

a. Ethan: We should all try to be more mindful of our actions.

b. Ethan: And that's what makes the planet hotter and hotter over time.

c. Ethan: Do you know what the greenhouse effect is and what it does?

d. Ravi: It's when gases in the air trap heat around the Earth.

e. Ravi: We can reduce our carbon footprint to help slow it down.

a. Tom: It's when we lose different kinds of plants and animals forever.

b. Carlos: My teacher told us about biodiversity loss today. It sounds scary.

c. Tom: Yes, often because we destroy their homes or hunt too many of them.

d. Carlos: Like when an animal becomes extinct?

e. Carlos: We need to protect all the different kinds of life on our planet.

a. Taylor: Yes, the rising temperatures of the ocean are making it happen.

b. Alex: It's terrible for all the fish and animals that live there.

c. Alex: Is that because of climate change?

d. Alex: I saw a program about coral bleaching. It looked so sad.

e. Taylor: It happens when the water gets too warm. The coral loses its beautiful colour and can die.

a. Sam: My mum bought a new bag that is made from recycled plastic.

b. Sam: It makes me want to recycle more things at home.

c. Jordan: It's a small change but it can have a big effect.

d. Jordan: That's great! Recycling helps a lot. It means we don't have to make so much new plastic.

e. Sam: And it keeps the old plastic out of the ocean where it hurts animals.

a. Jamie: I agree. We should turn off lights and the TV when we leave a room.

b. Chris: My dad says we should also unplug things we're not using.

c. Chris: We should be more careful about how we use power.

d. Jamie: Every little bit of energy we save helps the planet.

e. Chris: I think we use too much electricity and energy in our house.
